C++ errors

[Guest]

I decided to just fuck vb6 and gm6.1a and decide to move on to C++ seeing as how paying careers are more likely to happen with that language (and I don't give a damn if you have something to try and prove against me like "BUT VB IS THE MOST USED LANGUAGE EVARZZ!111!!! renzo joke"). Anyways, I am having errors with a simple tax calculator that I am making to try and get how this language works (it isn't so bad, if I knew wtf a non-lvalue was):

```
#include

using namespace std;

int main()
{
//variables
int item_cost;
int tax_rate;
int result;
int tax;

cout<<"Tax Calculator \n";
cout<<"How much does your item cost:";
cin>> item_cost;
cin.ignore();
cout<<"\n";
cout<<"What is your area's tax rate:";
cin>> tax_rate;
cin.ignore();
cout<<"\n";
cout<<"Calculating... \n";
if (tax_rate > 0) {
  return tax_rate = tax_rate/100;
  return item_cost * tax_rate = tax;
  return item_cost + tax = result; //line 26
  } //line 27
else {
    return item_cost = result;
    return tax_rate = 0;
    }
cout<<"Report: \n";
cout<<"Item Cost: "< Oh yeah, I use Dev-C++ and standard ANSI/ISO C++. The compiler reports non-lvalue in assignment on lines 26 and 27 (which I commented to help you find).
